FIELD: fire-fighting equipment.
SUBSTANCE: invention relates to fire extinguishing, namely to actuating system of shock-wave sprayers of fire-extinguishing compositions for automatic installation of pulsed fire extinguishing in oil and oil products storage tank. Actuating system consists of sprayers located along perimeter of oil tank and fixed on its side or on edge of floating roof, at that sprayers are made as shock-wave, pyrotechnic, double-sided spraying, recoilless; actuating system includes at least one sprayers salvo actuation subsystem; in the presence of two salvo subsystems, the second subsystem is configured to extinguish repeated fires, in the presence of more than two salvo subsystems, the subsystems are configured to be loaded with different fire extinguishing compositions to create a sequential combined extinguishing; sprayers are made of pipes separated in the middle by a tight coupling to form shafts, unitary spraying containers of bottle shape are inserted into the channels of the shafts with their necks tightly entering the coupling, the bottom part of each container is made as its least strong part in the form of a hemisphere, wherein in the cylindrical part of the neck there is a spraying cartridge, hermetically separated with a porous wad, behind which the container is completely filled with a fire-extinguishing composition.
EFFECT: disclosed is a system of recoilless shock-wave, double-sided sprayers of fire-extinguishing compositions for an automatic installation of pulse extinguishing in a storage tank for oil and oil products.
